One has to split the hair to find any difference between Changeux's theory of how the brain evolves and "learns" and Gerald Edelman's neural darwinism. Since they are both very convoluted writers, the task is virtually impossible on a scientific basis. The visible difference is that Edelman sticks to neuroscience whereas Changeux has philosophical ambitions and ventures into discussions of knowledge and morality as biological phenomena. But many of his conclusions are self-evident truths (i.e., that the brain is designed to manufacture objective knowledge, which obviously allows us to survive, whereas it would be more interesting to discuss why the same brain comes up with so many doubts, a fact that instead does not seem to contribute to our chances of survival).
